This Week in CFD

simscale-front-wingIt’s purely coincidental that the week we release Pointwise’s high-order meshing capability is also the week that ExaFLOW shares some of their high-order CFD work. And this week’s news is chock full of cool CFD applications from ship hulls, to heart valves, to race cars (exemplified by this beautiful SimScale visualization of flow over a car’s front wing). 

High Order

  • The ExaFLOW Project shares some of the ways they have helped advance high-order CFD including flow over the front wing of a race car. This article also includes the factoid that “10% of the energy use in the world is spent overcoming turbulent friction.”
  • Pointwise V18.2 was recently released with high-order (up to Q4), curved mesh generation.

Software

  • This could get interesting. The folks at Resolved Analytics will be writing “series of articles going into the nitty-gritty details on the pros, cons, capabilities and costs of many of the market leading CFD packages in each category. ” Stay tuned [for fireworks, hopefully].
  • MeshKit is “an open-source library of mesh generation functionality” from the SIGMA group at Argonne National Lab.
  • Beta CAE released v18.1.3 of their software suite.
  • SimScale Workbench 2.0 was a ground-up rewrite resulting in “the most advanced, yet user-friendly simulation interface version ever created by the cloud simulation company.”

When I saw the title of the article – “CFD – modeling without the mess” – I figured “mess” was a play on words with “mesh” so there’d be a lot of mesh generation bashing. Deep calming breath.]

Applications

  • CFD for turbochargers.
  • The University of Bristol is part of a team along with Rolls Royce and others who have been awarded 14.7 million for a 5-year research project to create a complete, high-fidelity simulation of an operating jet engine as the first step on the path to certification by simulation.
  • “The advances in computational fluid dynamics (CFD) modeling on high-speed supercomputers has reduced the demand for wind-tunnel testing but the modeling results are still not completely reliable and wind tunnels are used to verify CFD predictions.” From an article about a new transonic wind tunnel in China.
  • You can register to watch a Siemens PLM Software webinar on CFD for mechanical heart valves. [I don’t usually post news about webinars but I loved the image (see below).]
  • CFD for race cars. [Click through just to see the image of flow over a front wing. Also, is democratization of simulation really being led by cloud solutions for CFD?]
  • Award-winning application of CFD for coronary stenosis.
  • Advancing Regulatory Science with Computational Modeling for Medical Devices at the FDA’s Office of Science and Engineering’s Laboratories
  • In a video from the recent HPC User Forum, Intelligent Light’s Steve Legensky describes how FieldView brings together data science and CFD.

News & Jobs

  • Monica Schnitger reports on Aras’ acquisition of Comet Solutions and confirms that Aras users will get Comet at no additional charge.
  • I just subscribed to what looks like a new YouTube channel called Fluid Mechanics 101. One of their videos is How to solve the incompressible Navier-Stokes equations.
  • CHAM has an opening for a CFD engineer.
  • Xplicit Computing has openings for a CFD engineer and several C++ programming positions.

Pointwise User Group Meeting 2018

Pointwise_UGM_2018

  • It will be here before you know it so don’t delay, register today for the Pointwise User Group Meeting 2018 in Fort Worth on 14-15 November. Day 1 is chock full of seminars on use of the latest capabilities in the mesh generator. Day 2 is where our customers and partners [and us too] share applications, best practices, and future plans. There’s no fee to attend but registration is required.

Mountainous Mesh

Vancouver-based artist Laura Bifano says her paintings of mountains allow each of us to bring our own meaning to their “jagged expanses.” I’m certain you know what meaning I bring.
